BINDER AND METAL USED IN SAME 2 Sheets-Sheet 2 Filed Feb. 15, 1962ATTORNEY United States Patent 3,156,244 BINDER AND METAL USED IN SAMERobert F. Lindgren, Aurora, and Frank J. Malcik, Chicago, Ill.,assignors to Wilson Jones Company, Chicago, 111., a corporation ofMassachusetts Filed Feb. 15, 1962, Ser. No. 173,421 4 Claims. (Cl.129-12) This invention relates to a binder and to a metal used in thesame. The term metal is conventionally used to indicate the operatingparts of the binder and, in this application, the upper and lowercasings. It is not necessary for the part known as the metal to be madeof metal but the term involved is conventional in the binder art.

The metal of the instant invention is particularly adapted to beutilized in post binders which are the type of binder wherein aplurality of sheets are placed upon posts which project from one-half ofthe mechanism and wherein the other half of the mechanism is secured tothe posts.

In constructions of this type at least one of the casings of themechanism, since it must bear considerable pressure, must be made ofrelatively strong material. Where such a post is made pf steel thematerial has suflicient strength to prevent the casing from collapsing.However, if the casing is to be made of plastic, either in whole or inpart, the plastic does not have suflicient inherent strength to preventthe casing from collapsing. Since plastics have inherent superiorityover steel in many respects for this type of application including easeof manufacture, appearance, durability, etc., the instant invention hasbeen devised in order to provide a construction that would permit acasing framed with plastic material to have sufiicient inherent strengthto prevent it from collapsing.

In brief, the instant invention comprises a binder metal constructionincluding a casing and a corrugated support member within the casing.The binder metal, in the preferred modification, is framed with plasticmaterial, preferably high impact styrene and the construction includesboth an upper and a lower casing. The lower casing has a pair of spacedposts extending upwardly therefrom and the upper casing is provided witha pair of spaced holes each aligned with the corresponding post of thelower casing. Further preferred modification will be illustrated in thisspecification when the best mode of carrying out the instant inventionis specifically illustrated hereinafter.

The invention will be further described by reference to the accompanyingdrawings which are made a part of this specification.

The invention will be further described by reference to the specificform thereof which is shown in the accompanying drawings and whichrepresents the best mode known to the inventor for taking advantage ofhis invention. It must be understood however that this specific form ofthe instant invention is for illustrative purposes and for purposes ofexample only. Various changes and modifications may obviously be madewithin the spirit and scope of this invention and would occur to thoseskilled in this art.

In the specific embodiment shown, a binder 11 bears a metal 12 which isformed with an upper casing 13 and a lower casing 14. Upper cover 15 ishingedly secured to upper casing 13 by means of pin 16 which extendsthrough aligned openings 17 provided within upper casing 13.

Lower cover 18 is hingedly secured to lower casing 14 by means of a pin(not shown) which extends through aligned openings 19 within lowercasing 14.

Upper casing 13 and lower casing 14 are framed with plastic material 20which, in the preferred embodiment, is high impact styrene. The plasticmaterial is also molded into projecting cars 21 through which openings17 in upper casing 13 extend and through which openings 19 in lowercasing 14 extend. A pair of posts 22, preferably made of steel, aresecured to lower casing 14 and extend through casing 14 projectingupwardly. Upper casing 13 is also provided with a pair of openings 23which are aligned with posts 22 so that the corresponding post 22extends through the corresponding hole 23 as shown in FIG. 1.

At the end portions 24 of lower casing 14 and the end portions 25 ofupper casing 13 resilient bumpers 26 are attached. These bumpers aresecured in place by means of pins 27.

Both lower casing 14 and upper casing 13 are hollow. Upper casing 13 hasa locking portion 28 located at one end portion thereof. Upper casing 13also has corrugated member 30 secured thereto and longitudinallydisposed therein extending intermediate said locking portion and theopposite end portion of upper casing 13. Corrugated member 30 is securedwithin upper casing 13 by rivet 31.

Locking portion 28 is formed with support portion 51 and screw 32 isturnably disposed therewithin. Screw 32 has shaft 33 thereupon which ispreferably squareshaped and can be turned by means of key 34. Theforward end portion 35 of screw 32 is adapted to extend into one ofholes 23 (FIG. 7) and will lock the correspond ing post into positionwhen operated.

With the foregoing description the operation of the instant inventionmay now be explained.

When it is desired to load the binder of this invention with sheets ofpaper (not shown) key 34 is disposed upon shaft 33 and is turned so thatportion 35 is clear of corresponding hole 23. At this point upper casing13 may be pulled clear of lower casing 14 and a plurality of sheets (notshown) having holes aligned with posts 22 can be disposed upon post 22to the limit of the capacity of the binder which is proportional to theheight of posts 22. Upper casing 13 is then replaced upon lower casing14 and is spaced from lower casing 14 by the thickness & of the sheets.In this position the upper part of posts 22 are disposed within holes23.

Upper casing 13 then is pressed down so that the sheets are held in firmposition between upper casing 13 and lower casing 14. The pressure uponupper casing 13 is taken up by U-shaped member 29 and by corrugatedmember 30 so that upper casing 13 does not collapse 1n use.

Key 34' is then placed upon shaft 33 and screw 32 turned until portion35 bears against one of posts 22 in a firm manner so as to lock uppercasing 13 into position. Key 34 is then removed and binder 11 is readyfor its normal use.

With the foregoing description the reader of this specification caneasily see how the objects of this invention are achieved.
